Optocouplers or optoisolators are devices that use light to transfer signals and data from one system to another within a piece of electronic equipment without a direct electrical connection.

We will be introducing the Avago’s Gate Driver Optocouplers and the typical application.

The FOD3120 and FOD3150 are, respectively, 2.5A and 1.0A output current gate drive optocouplers capable of driving 1200V/20A IGBTs and MOSFETs in solar inverters, industrial inverters and induction heating applications.

The FOD410, FOD4108, FOD4116 and FOD4118 series of zero-crossing TRIAC driver optocouplers lowers standby power up to 2W, allowing applications to meet stringent regulations such as the 1 Watt Initiative and ENERGY STAR.
